[0002] Currently, water cups are widely used as a tool for holding liquids in daily life. They can be found everywhere, from offices to schools, and even in people's hands. There are various types of water cups, including thermos cups and open cups. To facilitate one-handed operation for users such as those traveling, cycling, or climbing outdoors, the drinking spout of water cups is often exposed, making it easy for small particles such as dust and bacteria to enter. Furthermore, after drinking, the spout is often wet, making it easy for dust to attract and bacteria to grow. Therefore, there is an urgent need for a water cup that is effectively dustproof and easy to use with one hand. Summary of the Invention

[0003] The present invention provides a cup cover and a water cup to solve the problems raised in the above background technology.

In the initial state, the upper part of the straw 5 is located inside the straw accommodating chamber 12, and the dust cover 2 is located on the open side of the straw accommodating chamber 12, and the straw accommodating chamber 12 is in a closed state; when drinking water, the switch 3 is pushed horizontally, and the switch 3 drives the dust cover 2 to rotate around the cup cover and away from the open side of the straw accommodating chamber 12 by driving the transmission mechanism. At the same time, the transmission mechanism drives the straw 5 to rotate, and one end of the water outlet of the straw 5 rotates out of the cup cover from the open side of the straw accommodating chamber 12; after drinking water is finished, the switch is pushed in the opposite direction, the upper part of the straw rotates back to the inside of the straw accommodating chamber 12, the dust cover 2 rotates to the open side of the straw accommodating chamber 12, and the straw accommodating chamber 12 is in a closed state again, and the drinking port is sealed in the cup cover, which can prevent fine particles such as dust and bacteria from entering the water cup.

[0022] like Figure 4-5 As shown in Figures 9-11, teeth 21 are provided on the inner side of the dust cover 2, a straw gear 61 is fixed on the straw 5, and the transmission mechanism includes a fixed shaft 41, a rack set and a gear set sleeved on the fixed shaft 41. The fixed shaft 41 is fixed in the cup cover, the switch 3 is connected to the rack, the rack set is connected to the gear set, and the gear set is connected to the teeth 21 and the straw gear 61.

[0023] The rack includes a first rack 25 and a second rack 64, and the gear set includes a first gear 24, a second gear 23, a third gear 63 and a fourth gear 62. A rack slide 16 is provided in the cup lid body 1, and the second rack 16 is slidably mounted on the rack slide 16. The first rack 25 is located at the upper end of the second rack 64; the fourth gear 62 is fixedly connected to the lower end of the third gear 63, the third gear 63 is engaged with the second rack 64, and the fourth gear 62 is engaged with the straw gear 61; The second gear 23 is fixedly connected to the upper end of the first gear 24, the first gear 24 is engaged with the first rack 25, the second gear 23 is horizontally engaged with the transmission gear 22, the transmission gear 22 is engaged with the teeth 21, and the cup cover body 1 is provided with a boss 15 for mounting the transmission gear 22, and the transmission gear 22 is sleeved on the boss 15; optionally, the second gear 23 is engaged with the teeth 21, and the transmission gear 22 and the boss 15 are not provided.

[0024] Push the switch, and the switch pushes the first rack 25 to drive the first gear 24 to rotate. The second gear 23 rotates coaxially with the first gear 24. The second gear 23 indirectly drives the dust cover 2 to rotate through the transmission gear 22, so that the dust cover 2 rotates on the opening side of the straw accommodating chamber 12. At the same time, the switch pushes the second rack to drive the third gear to rotate. The fourth gear 62 rotates coaxially with the third gear 63. The fourth gear 62 drives the straw gear to drive the straw to rotate.

[0025] like Figure 2-3 As shown, the cup cover further includes a cup cover upper cover 7, and the cup cover upper cover 7 is mounted on the upper end of the cup cover body 1 by screws.

[0026] like Figure 6 As shown, the cup cover body 1 is provided with a dust cover receiving groove 13 located at one end of the opening side of the straw receiving cavity 12 .

[0027] like Figure 10-11As shown, the switch 3 is fixedly connected to the first rack 25, and a certain distance is set between the switch 3 and the second gear 64. The first rack 25 is provided with a groove 26, and a protrusion 65 is provided on the upper end of the second rack 64. The protrusion 65 is located in the groove 26. When the switch 3 is pushed forward, since the switch 3 is fixedly connected to the first rack 25 and a certain distance is set between the switch 3 and the second gear 23, the switch 3 first pushes the first rack 25 to move the protrusion 65 from the end close to the inside of the cup cover to the end away from the inside of the cup cover in the groove 26. At the same time, the switch 3 indirectly drives the dust cover 2 to slide a part from the side of the straw accommodating chamber 12 to the dust cover storage groove 13; after the opening part of the side of the straw accommodating chamber 12 is opened, the switch 3 is connected to the second gear 23. When the switch 3 is pushed back, the first rack 25 is pulled back, and the second rack 64 is pushed back, until the dust cover 2 is completely inserted into the dust cover receiving groove 13, the straw is completely rotated out, and the switch 3 is also pressed to the bottom. In the process of pushing the switch 3 backward, since the switch 3 is not directly connected to the second rack 64, the switch 3 first drives the first rack 25 to pull back and drive the dust cover 2 to slide out from the inner part of the dust cover receiving groove 13, and the protrusion 65 moves from the end away from the inner part of the cup cover to the end close to the inner part of the cup cover in the groove 26. Continue to push the switch 3 backward, the first rack 25 continues to pull back, and at the same time, the groove 26 drives the protrusion 65 to drive the second rack 64 to pull back until the switch 3 is fully restored, the straw is completely retracted into the cup cover and is no longer connected up and down, and the dust cover 2 completely closes the opening of the straw accommodating cavity 12.

[0028] Optionally, the switch 3 is fixedly connected to the first rack 25 and the second rack 64, the front section of the first rack 25 is provided with convex teeth and the rear section is not provided with convex teeth, and the front section of the second rack 64 is provided with convex teeth and the rear section is provided with convex teeth; when the switch 3 is pushed forward, the first rack 25 and the second rack 64 move forward at the same time. Since the front section of the second rack 64 is not provided with convex teeth and cannot drive the third gear, the first rack 25 first drives the dust cover to retract into the dust cover storage slot. When the second rack 64 and the convex teeth are engaged with the third gear, the second rack drives the third gear to drive the straw to rotate out of the side of the cup cover. When the switch is pushed backward, the first rack (25) and the second rack 64 move backward at the same time. Since the rear section of the first rack 25 is not provided with Because the raised teeth cannot drive the first gear, the second rack first drives the straw back into the cup lid. The first rack then drives the dust cover to the open side of the straw-receiving chamber 12. More specifically, the raised teeth of the first rack 25 and the second rack 64 can be completely staggered. That is, when the switch 3 is pushed forward, the dust cover is fully opened and the straw rotates out of the cup lid. When the switch is pushed backward, the straw rotates completely back into the straw-receiving chamber 12 and the dust cover rotates to the open side of the straw-receiving chamber 12. The raised teeth of the first rack 25 and the second rack 64 can also overlap. That is, when the dust cover is partially opened, the straw opens with the dust cover. When the dust cover is closed, the dust cover closes with the straw. The length of the overlapping section can be adjusted as needed, as long as the dust cover and the straw do not collide. The overlapping raised teeth of the first rack 25 and the second rack 64 can reduce the overall length of the racks.

[0029] So Figure 9-10 As shown, the straw includes a rotating part and a fixed part, the rotating part includes a drinking part 51 and a water inlet part 52, the drinking part 51 is connected to the water inlet part 52, the drinking part 51 is fixed to the upper end of the water inlet part 52, a vertically arranged through hole 14 is provided in the straw accommodating cavity 12, the cup cover is also provided with a water baffle 4, the water baffle 4 is fixed to the lower end of the cup cover body, the water inlet part 52 is located in the through hole 14 and passes through the water baffle 4, the straw gear fixed sleeve is arranged outside the water inlet part 52, when the straw rotates, the water inlet part 52 rotates, and the drinking water part 51 rotates with the water inlet part 52 as the axis, so that the drinking water part 51 rotates out of the outside of the cup body 8 to facilitate drinking.

[0030] So Figure 9-10As shown, the fixed part is fixed to the lower end of the water baffle 4, and the fixed part includes a vertical water inlet pipe 56 and a horizontal water trough 55. The vertical water inlet pipe 56 is connected to the horizontal water trough 55. The horizontal water trough 55 is provided with a circular slot. The water inlet end of the water inlet part 52 is inserted into the circular slot. A water hole 54 is provided on one side of the circular slot. A water inlet hole 53 is provided on one side of the water inlet end of the water inlet part 52. When the drinking port is located on the inner side of the cup cover, the water hole 54 is not connected to the water inlet hole 53. When the drinking port is rotated out of the outside of the cup cover, the water hole 54 is connected to the water inlet hole 53. The lower end of the vertical water inlet pipe 56 can extend to the water storage space inside the water cup.

[0031] The water through hole 54 and the water inlet hole 53 are located at the same horizontal height. When the straw is located inside the cup lid, there is a certain angle between the water through hole 54 and the water inlet hole 53, and the straw is not connected from top to bottom, so as to prevent the water in the cup from spilling out when the cup is inverted or bumped; the angle between the water through hole 54 and the water inlet hole 53 with the axis of the water inlet part 52 as the intersection point is equal to the angle of the drinking part 51 completely rotating out of the cup lid; when the straw is rotated out of the cup lid, the angle between the water through hole 54 and the water inlet hole 53 is zero, the straw is connected from top to bottom, and water can be drunk directly.

[0032] like Figure 6-8 As shown, the cup cover also includes a buckle 31, and the cup cover body 1 is provided with a switch mounting portion 11 and a buckle mounting portion 19. The buckle mounting portion 19 is located at the lower end of the switch mounting portion 11, and a spring mounting groove 17 is provided on the inner side of the switch mounting portion 11. The first spring 36 is fixed in the spring mounting groove 17 at one end away from the switch 3, and the switch 3 can slide in the switch mounting portion 11. A rack slide 16 is provided in the switch mounting portion 11, and the second rack 64 can be slidably installed in the rack slide 16. The switch 3 slides in the switch mounting portion 11 to push the second rack 64. A spring mounting hole 18 is provided at the lower end of the buckle mounting portion 19, and the second spring 37 is fixed on one side of the spring mounting hole 18 at one end away from the buckle 31. The second spring 37 is fixedly connected to a spring connector 35 at one end close to the buckle 31, and the spring connector 35 can slide in the spring mounting hole 18. The clip mounting portion 19 gradually expands from the inside of the cup lid to the outside. Near one end of the clip mounting portion 19, located near the inside of the cup lid, is provided with a rotational axis mounting slot 192 for mounting the rotational axis 32. Pressing the other end of the clip 31 causes the clip 31 to rotate downward about the rotational axis 32. A riser 34 is also provided at the lower end of the clip 31, and a riser accommodating cavity 191 is provided at the lower end of the clip mounting portion 19. When the clip 31 is pressed downward, the riser 34 contacts the riser accommodating cavity 191, further enhancing structural stability.

[0033] When the switch 3 is pushed, the switch 3 contacts the inclined side of the positioning protrusion 33 and presses down the buckle 31. The first spring 36 and the second spring 37 are compressed, and the switch 3 is pressed to the bottom. The switch 3 is disengaged from the inclined side of the positioning protrusion 33. The restoring force of the second spring 37 pushes the buckle 31 up to restore it to its original state, canceling the pushing force of the switch 3. The vertical side of the positioning protrusion 33 clamps the switch 3, so that the switch 3 is always pressed to the bottom. The straw is also outside the cup lid and connected from top to bottom, which is convenient for drinking. After drinking water, the buckle 31 is pressed down, the second spring 37 is compressed, and the switch 3 is separated from the vertical side of the positioning protrusion 33. The restoring force of the first spring 36 restores the switch 3, and the restoring force of the second spring 37 restores the switch 3 and the buckle 31; like Figure 1 As shown, a water cup includes the above-mentioned cup cover and cup body 8, and the cup cover and cup body 8 are connected by threaded connection.

[0034] In the above-mentioned process, one only needs to pick up the water cup with one hand and press the switch 3 once to drink water immediately, and press the buckle 31 once more to restore the original state, thus achieving dustproof and water-proof spillage. The present invention has a simple operation mode, an ingenious structure, and realizes multiple functions, which is very conducive to popularization and use.
